WIX EXPERT - ADDING A FUNCTIONALITY

Hi, I hired a developer to add a request a quote button to my products and create a form as a link. I was in the process of adding my products and finishing up my website. But now that I am testing all the functionalities, I realized that the request a quote button under each product does no link the product to the form. Basically, if someone uses the request a quote button for any of my products, I won't even know which product they are requesting the product for. I need professional help in adding this functionality to the form. The product reference code ( sku ) needs to automatically linked to the form. I am not looking for just an added field on the form where the customer can enter the sku manually ( since they won't even remember what the sku number is ). I am looking for a way to automatically link the sku number to the form. I would want that the customer chooses ALL the products that they want to request a quote for by adding them to a cart then request a quote for all the products.
